Having problems with your Air Conditioners ?
Fan on outside unit will not start on its own.
Either your fan motor or capacitor is bad. The capacitor provides the motor with a phase imbalance to start it spinning. If it is shutting off this is because the motor is over amping and getting hot. You can try replacing just the capacitor to see if this corrects the problem but most likely the motor is bad by this point. When you replace the motor, replace the capacitor as well!!!

The outside unit is no0t able to start the fan spinning on its own. I have been able to manually engage the outside fan by turning the unit off, turning it on, and then manually spinning the fan when it starts up. The unit will then engage the fan and runs fine until the next cycle when it cannot start the fan on its own again. Can you tell me what part needs to be replaced and about how much it will cost?

My unit is running but not blowing cool air. I went outside and the condenor fan was not moving. Took a stick and shoved a blade and the fan started moving but the air is still not cool inside. I did notice the air coming through the unit outside after fan was blowing was cooler than my 2nd a/c unit that was working fine. I wondered if the entire unit was frozen. I turned off unit at thermostat and figured I would see what happens tomorrow
Sometimes on new units it is common for the fan to not start until you give it a push. Did you happen to hear if the compressor was operating? If the unit was froze-up the Insulated Suction line would also be iced over as well. If it wasn`t it is mor ... Carrier 38CKC024 Air Conditioner
I have a 561c central air unit. I just replaced the fan motor and capacitor 6 days ago. The unit ran great for just that long now the fan won't come on and the outside unit is hot to the touch, I can assist the fan and it starts and runs great until it reaches the thermostat temp. When it turns off it won't come back on. Is it the start relay switch?
Sounds like you need another capacitor since it will run if you turn it by hand to get it started. If you have a clamp on ammeter check the current draw on the fan motor. ... Air Conditioners
When calling for cold air, the fan in the cooling unit hums, but does not spin. With a nudge, the fan does spin. Looks to be smooth and normal speed. However ambient outside air 80 degrees. the air through the register is 72 degrees. Is there a switch that will not allow the fan to start on its own if the coolant is too low? Do I have two problems, fan starting AND insufficient cooling? Unit worked well the last two days.

I turn on the Central A/C unit with the thermostat. The attic fan unit goes on and the system cools the house. When the system shuts down the fan unit shuts off but the outside compressor keeps running. The only way the outside compressor goes now off is when I flip the 240 switch on the main box. This just started. Is it a thermostat problem? Thanks.
Could be a thermostat problem but even more likely the contactor on the unit outside is stuck. In order to change this part you will have to get in to the outdoor unit. The contactor is the automatic switch that the thermostat energizes when the t ... Air Conditioners
Contactor not engaging to start condenser unit . When setting the thermnostat, i hear the click from the unit starting inside the house. Fans start and air starts blowing inside the house, but the condenser unit never starts. I tryed pushing the contactor by hand and then everything works find (cool house) as long as i keep the contactor pushed manually. Seems alike the 24 V (coil) bobine in the contactor is not been energize. When I tried the 24 V outside with a 24 V surce it worked fine. Thank
I would replace the contactor if you are getting 24 volts to the contactor and it isn't engaging therefore the magneto on the contactor is out and the contactor will need replacement. If you don't have 24 volts at the contactor then the transformer ... Air Conditioners
My compressor unit outside runs and cools Freon but the inside blower has a problem running. the model # is 2TEE3F31A1000AA. The fan control, in fan run control mode, shows a bright green for the fan LED and the CFM selection LED varies with the rotational speed of the fan. The motor tries to start showing , initially, a jerky back & forth movement. It squeaks some and may, or may not, start rotating. If it starts the CFM LED goes bright/on no flicker and the motor runs briefly (5 seconds) then

My A/C outside will not run, inside a fan is blowing air (a little cooler than the 82 degrees it is in here, but not cold). Unlike all the other posts I've read, my unit outside is not making any noise. I makes a click when I turn it on at the termostat 1 time and then nothing.
